Many people participate in Internet listservs or newsgroups. Be
aware that it is possible to track the messages you have posted on such Internet
discussion groups.

For example, at the Dejanews Web site, one can search a person's name
or email user name and obtain a list of messages that the person has posted on various
listservs or newsgroups. After clicking on a message, there is an option to request
an "author's profile."

The author profile will list all the postings sent to various newsgroups
by that person (see example below). The "author profile" is one way of
finding out a person's interests and participation in newsgroups and listservs.
